[FILLING-MACHINE.

Specification of Letters Patent.

Patented Dec. 5, 1911.

Application filed January 18, 1911 Serial No. 603,390.

To all whom'it may concern:

Be it known that I, HENRY M. PARKER, a citizen of the United States ofAmerica, residing at VVillets, in the county of Jackson and State ofNorth Carolina,have invented new and useful Improvements in Tilling-Machines, of which the following is a specification.

This invention relates to implements for tilling the soil, and it hasfor its object to produce a simple and eflicient machine which by asingle operation or passage will break and turn the soil, cut or dividethe slices and break up or pulverize the clods, thus leaving the soil inthe best possible condition for subsequent planting and cultivation.

With these and other ends in view which will readily appear as thenature of the 1nvention is better understood, the same consists in theimproved construction and novel arrangement and comblnation of partswhich will be hereinafter .fully described and particularly pointed outin the claims.

In the accompanyingdrawings has been illustrated a simple and preferredform of the invention, it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterationsand modlficajtions within the scope of theclaims may be resorted to when desired.

In the drawings :Figure 1 is a top plan view of a machine constructed inaccordance with the invention. Fig. 2 is a longitudinal sectional viewshowing the machine arranged for transportation. Fig. 3 is alongitudinal sectional view, showing the machine arranged for operation.Fig. 4 is a transverse sectional view taken on the line 44 in Fig. 1.Fig. 5 is a transverse sectional view taken on the line 55 in Fig. 1.

. Corresponding partsin the several figures aredenoted by likecharacters of reference. The main carrying frame of the improved machineincludes side beams 1, 1 which are connected together at their frontends by a cross bar 2. The said side bars are provided near their rearends with boxes or bearings wherein the rear axle 8 is supported forrotation, said axle being provided with traction wheels 4, 4 which aremounted loosely upon the ends of the axle. The axle is provided withratchet wheels 5 that are 'engaged by spring actuated or resilient pawls6 which are mounted upon the traction wheels, said pawls and ratchetsconstituting clutches whereby the traction wheels will rotate the axlewhen. the machine is traveling in a forward direction, while whenthemachine is moved rearwardly the pawls will slip idly over the ratchets.

A separate front frame is provided which consists of side beams 7, 7lying adjacent to the outer faces of the side beams l of the maincarrying frame with which. the side beams 7 are pivotally connected bymeans of bolts 8 a short distance in front of the rear axle 3. The frontends of the side beams 7 are connected together by a cross bar 9 havinga bracket lO wherein the vertical stem or shaft 11 of a caster wheel 12is journaled, said caster wheel constituting a guide wheel andsupporting the Wheelfor the front end of the machine;

The side beams 7 are provided near their front ends with uprights 13connected by a cross bar 14 having a slotted bracket 15 wherein a bellcrank lever B is fulcrumed, said bell crank having a forwardly extendingarm 16 which is connected by a link 17 with the cross bar 2 of the maincarrying the ends thereof with lugs. or exten- SlOIlS 21 overlapping theside beams 7 of the front frame and adapted to rest upon said sidebeams, thus preventing the front end of the main carrying frame fromdropping below a predetermined point. Hingedly connected with theunderside of the front beam 2 of the main carrying frame are a pluralityof rearwardly extending bars 22, the rear ends of which are connected.to-

gether by a cross bar 23. A lever 24, which is fulcrumed upon the crossbar 2, is connected by means of a link 25 with the cross bar 23, thusenabling the rear ends ofthe longitudinal bars 22 to be simultaneouslyraised or lowered. The lever 24 is adapted to engage any one of aplurality of notches 26 in a rack bar 27 mounted upon and extendingupwardly from a cross bar 28 of the maincarrying frame, thus enablingthebars 22'to be secured at various adjustments.

Suitably connected with each of the bars 22 is a beam 28 carrying anearth engaging implement, such as a plow 29, which may be of any typedesired, such as an ordinary turning plow, a disk or a bull tongue. Itis obvious that by manipulating the lever 24, the plows may be set so asto operate at any desired depth in the ground, and that by manipulatingthe bell crank B the front end of the main carrying frame may be raisedor lowered so as to lift the plows out of engagement with the ground orto lower them for operation, as may be desired.

A rocking beam 30, which is supported for oscillation in brackets 31depending from the side bars of the main carrying frame, is equippedwith a plurality of downwardly extending knives or. cutters 32, each ofsaid cutters consisting of a blade fitted in a notch 33 in. the rockingbar and bent at its upper end to form a laterally extending arm 34through which a fastening member, such as a screw or bolt 35, extendsinto the body of the rocking bar, thus securing the knife blade securelyin position in an extremely simple and effective manner. The rocking baris provided with a forwardly extending arm 36 which is connected by aspring 37 with a bracket 38 that extends forwardly from a cross bar 39of the main carrying frame, the tension of the spring 37 being exertedto move the knives or blades in a forward and upward direction. Therocking bar 30 is provided at the ends thereof with forwardly extendinglugs 40, and turn buttons 41 are pivoted upon the brackets 31 whichsupport the rocking bar. These turn buttons may be disposed in the pathof the lugs 40, thereby limiting the movement of the blades 32 in aforward direction, and this is the normal operative position of therocking bar and the blades carried thereby, said blades being disposedin a substantially vertical position so as to cut into the soil, as willbe readily understood. If obstructions are encountered, such as stonesor the like, the blades are free to yield in a rearward direction. If itis not desired to use the blades, the turn buttons 41 may be moved outof the path of the shoulders upon the rocking bar, and the tension ofthe springs will then rock the bar so as to move the blades in a forwardand upward direction where they will be supported in a non-engagingposition with reference to the ground. The side bars of the maincarrying frame are provided in rear of the rocking bar 30 with bearingsfor a pair of shafts 43, 44, the ends of which are provided withintermeshing gears 45, 46. These shafts are also provided with radiallyextending earth engaging teeth 47 arranged in staggering relation, sothat the teeth upon the two shafts will intermesh and operate tothoroughly crush and disintegrate any clods that may be-subjectedto-their action. The

rear axle 3 carries a spur wheel 48 meshing with a pinion 49 upon acounter shaft 50, the latter carrying also a spur wheel 51 meshing withone of the gear wheels 46 upon the rear tooth-carrying shaft 44, thustransmitting motion to said shafts from the rear axle when the machineis in operation. A seat 52 for the driver or operator may be provided,said seat being preferably mounted upon a resilient supporting bar 53which is suitably connected with the main carrying frame. Draftappliances of any approved character are also to be provided, it beingunderstood in this connection, however, thatthe machine may, if desired,be propelled by a mechanical motor of any suitable construction.

From the foregoing description, taken in connection with the drawingshereto annexed, the operation and advantages of this invention will bereadily understood. It will be seen that the plows will turn the soil infront of the blades 32, the latter being so arranged or disposed as tocut lengthwise through the slices that have been turned by the plows.The soil will next be subjected to the action of the clod breakingdevices consisting of revolving toothed shafts which operate in oppositedirections, so that the clods will be thoroughly pulverized by theaction of the intermeshing or interengaging teeth. The forward end ofthe main carrying frame may by manipulating the bell crank be liftedsufliciently to support all the operating parts of the machine at aproper elevation above the ground to enable the machine to beconveniently transported from one place to another. Again, by means ofthe bell crank lever the forward end of the main carrying frame may belowered until the various implements are supported in the properposition to engage the ground. The plow carrying bars may beindependently adjusted by means of the lever 24 to set the plows tooperate at the desired depth in the ground.

Having thus described the invention, what is claimed as new, is

1. In a machine of the character described, a main carrying framecomprising side members and a front cross bar having overhangingterminal lugs, a wheel carrying axle supporting the rear ends of theside members, a front frame including side members pivotally connectedat their rear ends with the side members of the main carrying frame ashort distance in front of the rear axle, and a cross bar connectingsaid side members, a guide wheel connected with the cross bar to supportthe front end of the front frame, uprights rising from the side membersof the front frame, a cross bar connecting said uprights and having adepending slotted bracket and a forwardly extending ratchet bar,"a bellcrank fulcruined in the slotted bracket and having an upwardly and aforwardly extending arm, a pawl pivoted upon the upwardly extending armand engaging the forwardly extending ratchet bar, and a link connectingthe forwardly extending arm of the bell crank with the front cross barof the main carrying frame.
